It was erected by the Byzantines in the 9th century and must certainly be identified with the Εὐσάκτωρ of Notitia III or the Diatiposis of Leo VI the Philosopher, which Grimaldi erroneously identified with Uria or Míria near the river Smeri, and Minasi even with Oria in Apulia. A Greek document of 1164, published by Holtzmann (in Byzant. Zeitschr., 26 [1926], pp. 341 ff.), removes all doubt, since in it Robert, bishop of U., signs himself as ἐπισκόπος Εὐσάκτος. The existence of a bishop of U. ordained by Hilary, archbishop of Reggio, in the time of Sixtus III, i.e., in the 5th century, asserted by Ughelli and accepted also by Gams, is purely fanciful. Before the 8th century there were no metropolitans in Calabria, and U. was raised to a diocese by the Byzantines together with the metropolitan see of S. Severina. Among the five tiny suffragan sees of this metropolitan see, U. had the largest extent and included within its territory the city of Corò, birthplace of Luigi Giglio, the designer of the Gregorian calendar reform. In 1818 it was suppressed and its territory was aggregated to that of Cariati, which in turn had succeeded Cerenzia.
